Here we look at the top ten tallest buildings in the world and celebrate the monumental strides humans are currently making in the fields of construction and engineering. The barrier of a 2,000ft-tall building has already been broken and the first building set to go above 1,000 metres (3,280 feet), the Kingdom Tower in Jeddah, Saudi Arabia, is already under construction and set to open in 2019. That will take buildings past another major milestone in height, but until then let’s look at the ten tallest buildings in the world today, counting down to number one…
10 WILLIS TOWER
Height: 1,451ft (442m)
Other names: Formerly known as Sears Tower
Cost EST: $175million
Chicago’s Willis Tower was the tallest building in the world for nearly 25 years. Finished in 1973 following a three-year construction period, it held the title until 1998 when the Petronas Towers in Kuala Lumpur (see number 8 on this list) took the crown.
It has 108 stories with an observation deck on the 103rd floor, which is visited by more than a million people every year.
In May 1981 climber Dan Goodwin scaled the outside of the then Sears Tower while dressed as Spider-Man and using suction cups and safety gear. He was arrested at the top.
Then in August 1999 French freeclimber Alain Robert scaled it again without any safety gear at all, and using just his bare hands and feet. It was renamed Willis Tower in 2009 after the Willis Group took out a lease in the building. It has also been the home to the headquarters of United Airlines since August 2012.
9 ZIFENG TOWER
Height: 1,480ft (450m)
Other names: Greenland Center-Zifeng Tower, Greenland Square Zifeng Tower, Nanjing Greenland Financial Center
Cost EST: $1billion
The Zifeng Tower has 89 stories and houses office space as well as several restaurants and a hotel. There is also a public observatory on the 72nd floor offering spectacular views of Nanjing on a clear day.
It was designed by architect Adrian Smith from American firm Skidmore, Owings and Merrill. The geometry of the building follows the pattern of existing roads around the site. There are several sky gardens at various levels up the tower.
The InterContinental hotel starts on the 49th floor and stretches up to the 71st. Special structural safetyguards were put in place when building the tower as Nanjing lies in a seismic zone, meaning it is at risk of earthquakes.
8 PETRONAS TOWERS
Height: 1,483ft (452m)
Other names: Petronas Twin Towers/Menara Petronas/Menara Berkembar Petronas
City: Kuala Lumpur
Cost EST: $1.6billion
The Petronas Towers could count as two separate buildings, but we have put them together on this list as they are connected on the 41st and 42nd floors by a skybridge. They were the tallest buildings in the world for six years, from 1998 to 2004 until the crown was taken by Taipei 101 (see number 5).
Because the towers move in the wind and in different temperatures, the skybridge actually moves in and out of both the towers to stop it breaking. The final scene of 1999 film Entrapment, starring Sean Connery and Catherine Zeta-Jones, was filmed on the skybridge.
The towers were designed by Argentine American architect Cesar Pelli. In September 2009, French free climber Alain Robert climbed the outside of the second tower without any ropes or safety gear.
It took him just under two hours. He had previously tried the stunt in March 1997 and March 2007, but both times ended up getting arrested on the 60th floor.
7 INTERNATIONAL COMMERCE CENTRE
Height: 1,588ft (484m)

The ground floor of the International Commerce Centre building is occupied by a shopping mall called Elements. The skyscraper was designed by Kohn Pederson Fox Associates.
Six people died in an elevator shaft accident during the construction. The budget for the ICC Tower was shrouded in secrecy, and it wasn’t even revealed to the architects themselves.
